True, when I met her at the restaurant, she was indeed not a debutante..
Many, many moons ago, I saw her in a double bill with Tears for Fears as a solo act, though she of course played all her songs from Blondie. I believe that was 1990.
She came out for the encore with a full length fur coat on, then dropped it half way through the song to show off her bikini. What a fun show.
